Recently Oracle introduced “Autonomous Health Framework”. Oracle Autonomous Health Framework contains Oracle ORAchk, Oracle EXAchk, and Oracle Trace File Analyzer.

You have access to Oracle Autonomous Health Framework as a value add-on to your existing support contract. There is no additional fee or license required to run Oracle Autonomous Health Framework.

In this article we will learn how to Install, setup and execute AHF for Oracle Exadata Database machine in detail.

Step 1: Download AHF for Linux operating system as shown below. Here we are using the wget command to download file directly to the server. If you don’t have proxy you can download the file MOS to your desktop and copy it the server using WinSCP.

[root@dm01db01 ~]# cd /u01/app/oracle/software/

[root@dm01db01 software]# mkdir Exachk

[root@dm01db01 software]# cd Exachk/

[root@dm01db01 Exachk]# export use_proxy=on

[root@dm01db01 Exachk]# export http_proxy=”webproxy.netsoftmate.come:80/”

Download the AHF zip file

[root@dm01db01 Exachk]# wget –http-user=abdul.mohammed@netsoftmate.com –http-password=************ –no-check-certificate –output-document=AHF-LINUX_v20.1.1.zip “https://updates.oracle.com/Orion/Services/download/AHF-LINUX_v20.1.1.zip?aru=23443431&patch_file=AHF-LINUX_v20.1.1.zip”

Download the latest cvu. This will be used by the exachk to run the cluster verification

[root@dm01db01 Exachk]# wget –http-user=abdul.mohammed@netsoftmate.com –http-password=************ –no-check-certificate –output-document=cvupack_Linux_x86_64.zip “https://download.oracle.com/otndocs/products/clustering/cvu/cvupack_Linux_x86_64.zip”

-rw-r–r– 1 root root 293648959 Jul 13 2018 cvupack_Linux_x86_64.zip

Step 2: Unzip the AHF zip file

[root@dm01db01 Exachk]# unzip AHF-LINUX_v20.1.1.zip
